A bag contains 10 marbles which can be described by Colour and whether it is numbered or lettered as follows:
4 are white and lettered, 2 are white and numbered, 3
yellow and lettered and 1 is yellow and numbered. One marble
is randomly drown from the bag and is found to be white.
what is the probability that it is numbered?​

the answer is b

66.666666667%

step-by-step explanation:

divide 150 by 100

divide 100 by 1.5

there you go!

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.

isn't it a pentagon? sense [3 (triangle) + 4 (rectangle)] - 2 (triangle and rectangle connected) = 5 (pentagon)
